Q: Lost half a tank of fuel in less than 2 miles. the tank is empty. can't see a leak

Coming home from a job i got off the freeway and checked my gas gauge about half way from the off ramp to my house, it showed half a tank, i had just the day before filled it up and only traveled 112 miles on a nearly full 28 gallon tank. about half a mile from my house the low fuel light came on and the gauge showed empty, way below the 'E'. i didn't smell any fumes or have any loss of power so i thought something was wrong with the Gauge or electronics. As i backed into my driveway the truck died. i got out and looked under the truck and under the hood and didn't see any leakage and no gas odors at all. I loosened the gas filler cap and there was pressure in the tank, it blew air (and fumes) OUT of the tank as i unscrewed the filler cap. checked as many of the fuel lines as i could see and found nothing disconnected or split. I don't see any holes in the tank either
